Parker's PR Series Plug Valves provide positive leak tight shut-off, high flow capacity, and quick quarter-turn operation in a compact, barstock body. This plug valve provides the user the ability to throttle during manual actuation. Parker's PR Series Plug Valves provide positive leak tight shut-off, high flow capacity, and quick quarter-turn operation in a compact attractive package. The patented blow-out resistant seat design offers reliable sealing technology at all operating pressures not seen in general purpose plug valves. In addition to on-off actuation, the plug design allows forward flow throttling. A broad selection of valve seats and seal materials may be chosen for media compatibility and performance over a broad range of temperatures. The pressure balanced atmospheric seals are backed by PTFE rings to enhance their performance and increase cycle life.
